But in a statement Sunday morning, Dinolfo said she decided against seeking the lieutenant governor nod after consulting with her family.

Hours later, Molinaro — who is hoping to unseat Democratic Gov. Andrew Cuomo this fall — announced who will be his running mate: Julie Killian, a former Rye deputy mayor and state Senate candidate from Westchester County.

"I am humbled by the kind words of support I received from across the state, but after a great deal of reflection with my family, I will not be seeking the Republican nomination for Lieutenant Governor this year," Dinolfo said in her statement.

Dinolfo helped lead Molinaro's vetting process for lieutenant governor, speaking with more than 20 potential candidates and advising the Dutchess executive on his choice, according to Molinaro's campaign.

"(Dinolfo) is a tremendous leader and I am grateful for her support, assistance, leadership and friendship," he tweeted.

In her statement Sunday, Dinolfo said she enjoyed her vetting role with Molinaro's campaign and pledged to "working with him when he becomes governor next year."

She is up for re-election next year.

"As someone who has lived, worked, and raised a family here, serving as Monroe County executive is an incredible honor, and I remain committed to keeping our community in good hands in 2018 and beyond," Dinolfo said.
